Selection Of The Off2 Command Source; Inhibiting Negative Set Points Of Mop; Co: Frequency Setpoint Before Rfg; Ramp-Up Time - Siemens SINAMICS V10 Operating Instructions Manual

Parameter list
Par. No. Name
P0844

Selection of the OFF2 command source

Note: If P0840 and P0844 are wired together by the same input (i.e. P701 = 99; P0840 = 722.0; P0844 = 722.0), then the
input will act as the ON/OFF2 function. OFF2 has a priority to OFF1.
P1032

Inhibiting negative set points of MOP

Possible settings:
0
1
Note:
The reversing functions are not affected by the settings of P1032, which only restrict an MOP setpoint. Please
use P1110 to fully prevent any change of direction in a setpoint channel.
Setting P1110 to 1 will set P1032 to 1 automatically.
Setting P1032 to 1 will reset the saved negative MOP value (if P1040 < 0.0) to 0.0 automatically.
r1119

CO: Frequency setpoint before RFG

Displays output frequency after modification by other functions, e.g.:
● P1110 BI: Inhibit neg. frequency setpoint.
● P1091 skip frequencies.
● P1082 Min frequency.
● P1082 Max. frequency.
● Limitations
● Etc.
P1120

Ramp-up time

Time taken for motor to accelerate from standstill up to maximum motor frequency (P1082) when no rounding
is used.
Note :
● Setting the ramp-up time too short can cause the inverter to trip (overcurrent).
● If an example frequency setpiont with set ramp rates is used (e.g. from a PLC), the best way to achieve
optimum inverter performance is to set ramp times in P1120 and P1121 slightly shorter than those of the
PLC.
P1121 Ramp-down time
Time taken for motor to decelerate from maximum motor frequency (P1082) down to standstill when no
rounding is used.
P1130 Ramp-up initial rounding time
Defines initial rounding time in seconds as shown on the diagram below.
